Last week the oil shock changed the mix of what went up and down; this week it started lowering prices. WTI rose another 9.37% to $100.05, a second straight gain of about 9%, and the ten-year yield rose 19 basis points to 4.97%. The S&P 500 fell 0.80% to 7,657, the Nasdaq 100 0.59% to 29,368 and the Russell 2000 2.41% to 2,904. Small caps, the most sensitive to borrowing costs, fell three times as much as the large-cap index: the pattern you get when rates do the damage rather than earnings. Nine of eleven sectors finished red, gold fell 0.47% and bitcoin 3.14%. Nothing worked as a hedge.
Macro Overview
Friday's August CPI decided the Fed question and also rescued the week. Core prices rose 0.3% on the month, a tick above the 0.2% consensus, while the annual core rate eased to 2.4% from 2.5%. The market priced a 25-basis-point hike at next week's meeting at roughly 85–90%, up from ~63% after payrolls a week ago. Stocks still rallied Friday (S&P +0.9%, Nasdaq +1.0%) as Brent slipped off a four-month high; on a Thursday-close basis the week was meaningfully worse.
The biggest move had nothing to do with oil or rates. Amgen fell 13.70%, including a 10.08% drop on Tuesday, its steepest one-day fall since October 2000. Novartis's pelacarsen lowered lipoprotein(a) but failed to cut heart attacks, strokes or cardiovascular deaths in its Phase III outcomes study, a class-wide scare for Amgen's olpasiran, and UK regulators suspended new patient starts on Tavneos. Booking Holdings (-9.80%) and S&P Global (-7.40%) were the next largest losses.
The AI buildout's physical layer got its test: hold green through a week when Nvidia was flat or down. Nvidia fell 5.13%; Eaton rose 3.53%, American Tower 1.14%, Equinix 0.17% and Digital Realty 0.10%. The power leg did not hold (Constellation -4.75%, NextEra -1.34%), though a 19bp rise in the ten-year is reason enough for any utility to fall. AMD rose 8.07%, the largest gain in the universe. The trade is rotating inside the AI stack, not leaving it.
Sector Overview
Health Care (XLV) -3.55%, Worst sector, two of ten names green. Amgen's fall was about a drug class, not a quarter; Abbott (-5.89%) and UnitedHealth (-4.55%) show it was not one stock. Abbott is in the loser column a third straight week with no catalyst identified. Top: AMGN -13.70%.
Materials (XLB) -2.84%, All ten names red as higher feedstock costs, a stronger rate headwind and a weaker demand signal hit at once. The farm-complex run broke: Corteva ended three green weeks as Deere stalled with it. The cycle call is no longer strengthening. Top: CTVA -4.51%.
Consumer Discretionary (XLY) -1.70%, The EU General Court upheld the veto of Booking's €1.63 billion ETraveli deal, on top of a cut growth guide and $100 crude. TJX (-4.59%) sold rather than bid: households are cutting back, not trading down. Tesla (+3.21%) was the only green name for a second week. Top: BKNG -9.80%.
Energy (XLE) +1.69%, The only real gain, again a fraction of WTI's +9.37%: about four points over two ~9% crude weeks, so the war premium is priced as temporary. Leadership moved from refiners to producers; services (SLB -2.52%) and midstream lagged. Top: XOM +4.09%.
Industrials (XLI) -1.65%, Eaton (+3.53%) held green a second week while Nvidia fell 5.13%, the strongest evidence yet that grid and data-center power equipment is valued on its own order book. GE (-3.99%) carried the flight-hours exposure. Top: UBER -5.40%, as fuel rose again.
Utilities (XLU) -1.60%, All ten names red as the ten-year rose 19bp, a mild bond-proxy response. Constellation gave back just over half of last week's +8.03%, trading like a utility while the equipment and landlord legs held. Top: CEG -4.75%.
Financials (XLF) -1.46%, S&P Global fell with no downgrade, guidance change or event: a continued derating of data-and-ratings franchises on growth and AI-disruption concerns. Berkshire, Wells Fargo and Bank of America were the only green names; the banks barely caught the rate rise. Top: SPGI -7.40%.
Consumer Staples (XLP) -1.42%, Philip Morris (+4.67%) almost exactly reversed last week's -4.88% as the defensive bid returned. Last week's value-retail trade reversed too, with Target the sector's worst. Top: TGT -5.24%.
Real Estate (XLRE) -1.16%, A mild loss against +19bp because the AI-infrastructure landlords, American Tower, Equinix and Digital Realty, finished green together. CBRE, a transaction-volume business, took the near-5% ten-year hardest. Top: CBRE -4.96%.
Communication Services (XLC) +0.51%, Meta rose a second week, ~12% over two, with no new catalyst beyond the Muse Spark 1.3 release: the market confirming the re-rating. Levered cable sold into the rate move (Comcast -4.87%, Charter -4.09%). Top: META +5.07%.
Technology (XLK) +0.21%, AMD against Nvidia was framed as rotation inside the AI chip trade, on the argument that agentic AI uses far more CPU. Adobe (-5.36%) beat on both lines and still sold; Oracle (-5.35%) reversed last week's run-up. Top: AMD +8.07%.
Next Week
The Fed meeting is a question of how the hike is delivered, not whether it comes. With a 25bp hike priced at roughly 85–90%, the guidance is what is not priced. Framed as a single insurance move against an oil-driven impulse, it likely brings relief to what this week punished: small caps, utilities, bond-proxy REITs and cable. Framed as the start of a cycle, it puts the ten-year through 5%. The same decision separates rates from the AI thesis: if power names recover while equipment and landlords hold, the theme is intact across the stack.
Crude at $100 is the other variable. Booking, Starbucks, TJX, Target and Uber remain effectively short the barrel, and a ceasefire headline would reverse them inside a session. No weekend development in the conflict or at Hormuz surfaced that changes Friday's picture; check before Monday's open rather than assume.
Three singles: Amgen, where any read on olpasiran's own outcomes timeline is now the stock; Abbott, where a fourth loser week would mark a specific problem, not noise; and S&P Global, where a continued slide would mean the market is repricing financial-information franchises as a class.
